SKP SAFE - group of insulating glass units involving the insulating glass units produced using safe glass.
Safe glass is laminated, tempered or reinforced glass.
When making design of windows and outside doors, the following should be taken into consideration:
Glass safety is described by classes of glass resistance to strokes and type of breakage.
Glass properties and classes defining glass properties in accordance with LST EN 12600:
|Resistance to stroke||3, 2, 1||3 class glass - lowest resistance to strokes,
1 class - highest resistance to strokes.
|Type of glass breakage||A||Glass breaks up into multiple different-sized sharp-edged pieces.
This feature of glass breakage is typical of the ordinary glass
hardener thermally and chemically.
|B||Glass can crack or break, but glass pieces remain stuck to the film.
This feature of glass breakage is typical of laminated glass covered
with films and wire grid.
|C||Glass breaks into multiple small pieces which are relatively harmless.
This feature of glass breakage is typical of thermally hardened glass.
The use of safety glass in Lithuania is regulated by Technical Regulations for Construction STR 2.05.20:2006 “Windows and outside doors”.
The following standards are used for classification of safety glass:
